Host-Based Diagnostics for Acute Infections

DISCLAIMER

This is an information request only. This request is issued solely for information and planning purposes – it does not constitute a Request for Proposal (RFP) or a promise to issue an RFP in the future. Solicitations are not available currently. This notice does not constitute a commitment by the United States Government to contract for any supply or service whatsoever.

Purpose:

Capability Program Executive for Chemical, Biological, Radiological and Nuclear Defense (CPE CBRND) invites you to collaborate with us in a critical mission: to develop the next generation of host-based assays for diagnosis of disease etiology, prognostication of clinical outcomes, and directed administration of therapeutic treatments that will protect the warfighter from chemical, biological, radiological, and nuclear (CBRN) threats.

This RFI is your opportunity to help shape the future of military medicine and contribute directly to the readiness and resilience of our armed forces. The decade-long surge in tracking host responses to pathogens has spawned diagnostic technologies that utilize specific panels of host response molecules to differentially diagnose the class of pathogen (e.g., bacterial or viral), predict the likelihood of severe illness and/or enable the selection of therapeutic regimen. The goal is to identify and develop a new generation of host-based test to diagnose a warfighter’s condition, predict clinical outcomes, and direct the optimum therapeutics for maximal disease recovery. This creates a prime opportunity for innovative companies to align their research and development pipelines with a forward-looking program.

Disclaimer: This is a Request for Information (RFI) for planning purposes only. It is not to be construed as a commitment by the Government, nor will the Government pay for the information solicited. No solicitation document exists or is guaranteed to be issue because of this RFI

Requested Information of Interest:

CPE CBRND is conducting essential market research for the Advanced Differential Diagnostics (ADD) program, an existing Program of Record that is developing new diagnostic capabilities in a phased approach. This program is dedicated to identifying and advancing mature diagnostics that utilize the warfighter’s early response to the pathogen. CPE CBRN will be focused on developing and delivering diagnostics that help meet operational and mission needs across the conflict continuum. The goal is to create a resilient force, capable of withstanding, mitigating, and recovering from the complex injuries caused by CBRN threats, some of which are outlined in the Medical Management of Biologic Casualties Handbook,  Medical Consequences of Radiological and Nuclear Warfare, and  Medical Aspects of Chemical Warfare.

We are seeking information from industry partners developing innovative solutions that diagnose infection based on measures of the body’s response rather than targeting specific pathogens. These tests will rely on host biomarkers to make diagnostic determinations, for example, peripheral blood cellular gene expression patterns, rather than direct detection of a pathogen. We are particularly interested in candidates that fall into the following categories:

• Predictive Diagnostics for Infection Complications: Diagnostic assays that are predictive for Sepsis, SIRS, respiratory destabilization, or other acute complications from infections of biowarfare agents, based on the patient’s current condition and measurable host biomarkers circulating in the peripheral blood or other easily accessible sample types.
• Diagnostics to assist in Therapeutic Selection and Monitoring: Diagnostics based on host biomarkers that enable precision medicine for the most appropriate treatment, or that reveal proper response to therapeutics or ineffective therapeutics, such as in hyperinflammatory states or immune response paralysis that may occur due to biowarfare agent exposure or other infectious agents. 

We are seeking mature candidates (preference for diagnostics at Technology Readiness Level (TRL) 4 or higher) that align with the following ideal product profile:

Example Target Product Profile for Host-Directed Products

This profile targets products designed to enable rapid diagnostic decision-making in remote laboratories or central clinical laboratories for suspected acute infections that may also direct effective therapeutic treatments to prevent severe outcome and/or monitor recovery.

Feature

Desired Characteristic

Intended Use:

Used with clinical assessments and other laboratory findings as an aid to determine the likelihood of severe clinical outcome in adults with suspected acute infections; and/or enlighten the selection of appropriate therapeutics. 

Device Size and Robustness:

Since the device is intended for low resource sites, the ideal size should be relatively small (handheld or backpack-sized), battery-operable and/or externally powered, operable in tropical humidity and temperature environments, with an assay time of less than 70 minutes and ideally less than 10 minutes.

Clinical Efficacy:

Diagnostic clinical sensitivity and specificity greater than 90% is desired.   Diagnosis and appropriate treatment lead to reduced severity and duration of clinical manifestation; improvement in clinical symptoms, reduction in length of hospitalization, and enhanced return to duty.

Sample Types:

Peripheral blood samples (EDTA or PAXgene-stabilized), fingerstick blood samples, respiratory samples, other minimally invasive sample types.

Administration:

Respondents are requested to submit a white paper, not to exceed three (3) pages, that addresses the following areas, in the order presented. A separate, one-page Quad Chart should also be included. It should contain the objective of the project and benefit of the product; a high-level development schedule with major goals/timelines; a Rough Order of Magnitude cost; and any associated Intellectual Property rights required for commercial marketing and use, patent coverage, commercial market, or data rights assertions.

The government’s primary interest is to identify scientifically mature and programmatically viable candidates. Therefore, when reviewing responses, the government will place the greatest emphasis on the “Technical Approach and Product Maturity” and “Regulatory and Clinical Status” sections. Responses that provide detailed, data-driven evidence in these areas will be considered most valuable.

1. Technical Approach and Product Maturity
   
   1. Product Description: Describe the host-directed response(s) that your candidate diagnostic targets, the specific gene expression or physiological pathways, and its intended use.
   2. Technology Readiness Level (TRL): State the product’s current TRL using the harmonized Quantitative Technology Readiness Level (Q-TRL) rating scale for diagnostics (https://medicalcountermeasures.gov/trl/trls-for-medical-devices) and provide justification for this assessment.
   3. Diagnostic Efficacy Data Summary: Please summarize significant performance data using banked, contrived, or clinical study samples. Specify the sample types, gene or other molecules targeted, and key outcomes (e.g., clinical sensitivity and specificity, outcome prediction efficacy, time-to-answer).
2. Regulatory and Clinical Status
   1. U.S. Food and Drug Administration (FDA) Engagement: Provide a concise history of all interactions with the FDA regarding this candidate, highlighting any formal feedback that informs development risk or regulatory strategy. Please include the status of any applications and any special designations received (e.g., Pre-Submission, EUA, 510(k)).
   2. Clinical Data / Trial History: Please detail any completed or ongoing clinical trials, including the number of human subjects, and any available clinical data. Similarly, detail any completed or ongoing studies involving clinical specimens. Describe any studies conducted with intended users.

1. Manufacturing and Supply Chain
